STOVEPIPE AND DRUM RADIATOR.

SPECIFICATION forming part of Letters Patent ,No. 776,589, datedDecember 6, 1904. Application filed February 2Q, 1903. Serial No.144,907. (No model.)

T0 at whom it may concern.-

Be it known that 1, JORDAN H. GREEN, a citizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,haveinvented a new and useful Improvement in Stovepipe and Drum Radiators,of which the following is a specification.

My invention relates to stovepipes and drums; and the object of myinvention is to furnish means for graduating the heat-radiating capacityof the pipe and drum. This object l accomplish by means of the deviceillustrated in the accompanying drawings, in whiclr- Figure 1 shows aside elevation of my device, partially broken away to show constructionof parts. Fig. 2 is a plan view, and Fig. 3 is a rear view, of the lowerportion.

Similar letters refers to similar parts in the several views.

A A represent a length of ordinary stovepipe, to which I attach a drum BB. The drum BB partially surrounds the pipe, and for more convenientlyfacilitating process of construction its shell extends entirely aroundthe pipe, as shown in Fig. 2, having enough of the ends of the pipeprojecting beyond the ends of the drum for the joints of the pipe. Thepipe is provided with openings A A and a vertical partition (3,extending from side to side of the pipe, dividing the pipe-flue a athrough a portion of its length into two fl ues A A The drum is closedby a bottom and top, thus forming a tight chamber 6, surrounding abouthalf of the pipe, as shown especially in Fig. 2. Communication betweenthis chamber 6 and the pipe-flue a a is by the openings A A and thedraft and heating capacity of the chambers are regulated by the dampersD and E. The damper D is semicircular, covering half of the pipe-flue,and is hinged close to the bottom of the partition (1, so as to open orclose communication between the lines a and A from below and between aand Z). The damper E is circular and when closed partitions the entirepipe-flue. A hand-hole is provided at the bottom end of the drum with acover, as shown in Fig. 3, for the removal of soot.

The operation of my, device is as follows: To obtain the greatestradiation, close both dampers D and E, and the smoke entering the flue ais diverted and passes successively up through the flue A over the topof the partition (3, down through the flue A, out through the opening A,up through the drumchamber 5, then through the. opening A, back into thepipe, and up out through the pipes flue a. To get the least radiation,close the bottom damper D and open the top one, E, and the smoke travelsup through the line A heating the least radiating-surface. To obtain amedium heat, open the bottom damper D and close the top damper E, andthe smoke will pass up into the drum-chamber 6, through A, thence backinto the pipe, through the opening A, converting the fines A and A intomerely conduction-chambers.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

The combination of a stove-pipe and a drum the chamber of whichpartially surrounds the pipe, the latter having a longitudinal partitionand two dampers, and having also passages into said drum-chamber,whereby the course of the products may be directly through the pipe,directly through the drum, or tortuously in the pipe and directlythrough the drum.
